It is indeed an opinion strangely prevailing amongst men, that houses, mountains, rivers, and in a word all sensible objects, have an existence, natural or real, distinct from their being perceived by the understanding.

A Treatise Concerning the Principles of Human Knowledge § 4

Berkeley was born near Kilkenny in Ireland in 1685, and at Trinity College, Dublin, he encountered the new science and philosophy. His notebooks show his immaterialism taking shape as he argued with Descartes, Locke, Malebranche, Newton and Hobbes. Before he was thirty he had published the books he is still read for, the Principles and the Three Dialogues.

He spent three years in Rhode Island waiting for funds to found a college in Bermuda, which never came. Later he criticised the foundations of Newton’s calculus in The Analyst, became Bishop of Cloyne in 1734, and in Siris promoted tar-water as a medicine. He died in 1753 in Oxford. Many of his first readers met him with incomprehension, but he influenced both Hume and Kant.

Key ideas

To be is to be perceived
Houses, mountains and rivers are things we perceive by sense, and we perceive only our own ideas, so ordinary objects are ideas. Their existence consists in being perceived; the idea of something existing unperceived is a contradiction.
No material substance
Berkeley attacked the belief that behind our ideas lies unthinking matter that they represent. Materialism, he charged, leads to scepticism, since our senses would mislead us about matter’s nature, and to atheism, since a material world could run without God.
Idealism and common sense
Reality consists only of minds and their ideas. Berkeley insisted this agrees with common sense better than materialism does: the things we see and touch are real, just as we perceive them.
God and the order of nature
The ideas of sense are not produced by us but by God, and they come in regular patterns. The laws of nature are simply the set rules by which God excites these ideas in our minds.
